My improved spreading device preferably consists of a tubular member I Within which are located twin grooved pulleys 2 mounted on a spindle 3, the open ends 4 of the tubular member be- Y ling flanged as shown at I2, and also reduced in diameter by the permanent attachment thereto of metal rings 5. These rings or ring members 5 extendjout a short distance within the tubular mem-ber, being spaced apart for the double pur pose of providing a raceway 6 for the spindle and at the same time retaining it with the pulleys thereon, in place, during the operation of the spreader. The pulleys are mounted side by side and, for the reason hereinafter described, the inner rim or ange of both is higher than echange (c1. zus-natali theiiwouterrimswmflanges: as show-mat.: Tf, and' substantiailwcontactwith caen-others.:

When the articles are ready to loe taken from the line they are released by the operation of the spreader in the reverse direction.

The elements of my spreader have been combined to produce what I consider to be a prac tically indestructible device and one that is adapted to operate smoothly at all times. The spindle or shaft is provided with a raceway which gives it a universal bearing. By this means the pulleys are allowed freedom of movement to respond to the pulls of the lines in various directions thus preventing the disruption or breakage which would probably result if the spindle or shaft were stationed in a fixed bearing. To avoid the jamming of the line in use I have elevated the inner flanges of the pulleys. By this means each of the two wires of the line is retained Ain its proper groove and jumping of the same from one pulley to another rendered impossible.

While a speciiic embodiment of the invention has been described, it is to be understood that various changes and modiiications may be made therein Without departing from the invention and the scope of the claims appended hereto.

I claim:

1. In combination in a spreader of the character described, a tubular member the interior of which is reduced in diameter at both ends, a pair ofspaced ring members positioned intermediate said'r'educed portions and forming with said tubular member a raceway, a spindle and a pulley movable thereon, said raceway receiving the ends of the spindle.

2. In combination in a spreader of the character described, a tubular member, a ring member permanently fixed to the interior of each open end of the said tubular member and spaced from each other, and located within the said tubular member, a spindle, two pulleys loosely mounted thereon, said ring members and the tubular member forming a raceway receiving the ends of the spindle.

3. In combination in a spreader of the character described, a tubular member, a. circular member permanently iixed to the interior of each open end of the said tubular member and spaced from each other, a spindle, two pulleys each. having a high inner ange and a lower outer flange and loosely mounted on the spindle, said circular members and the tubular member forming a raceway receiving the ends of the spindle.

4. In combination in a spreader of the character described, a tubular memberV whose ends are anged, a circular member permanently xed to the interior of each open end of the said tubular member and spaced from each other, a spindle, two pulleys each having a high inner iiange and a lower outer flange and loosely mounted on the spindle, said circular members and the tubular member forming a raceway receiving the ends of the spindle, and the said inner flange of each pulley substantially Contacting each other.

5. In combination with a line consisting of two members permanently twisted together and adapted to be under such tension in use as to maintain said members in close relationship, a spreading device comprising a tubular member, a circular member permanently xed to the interior of each open end of the said tubular member and spaced from each other, a spindle, two pulleys each having a high inner ange and a the tubular member forming a raceway receiving the ends of the spindle.

7. In combination with a line consisting of a plurality of members permanently twisted together and adapted to be under such tension in use as to maintain said members in close relationship, a spreader device comprising a tubular member whose interior vis reduced in diameter at both ends, a pair of spaced ring members positioned intermediate said reduced portions and forming with said tubular member a raceway, a spindle, two pulleys, each having a high inner ange and a lower outer flange looselyv mounted on the spindle, said ring members and the tubular member forming a raceway receiving the ends of the spindle.

8. A clothes hanging device comprising a clothesline having a pair of twisted strands, and a strand separator mounted thereon, said separator comprising a cylindrical hollow body, an axle having pulleys rotatably mounted thereon and separately engaging said strands, said body having means providing an annular raceway, in a plane perpendicular to the strands, which receives the ends of the axle. v
